Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Insider

  • Delivery depends heavily on the assigned account team, so results vary by region and a team change mid-contract can be felt immediately in campaign output.
  • The suite is licensed by module, so the platform fee quoted at the start typically excludes the channels and predictive features that make the business case work.
  • Template-driven web personalisation targets the rendered DOM, which breaks on single-page applications that re-render after the template applies unless a developer wires in the framework hooks.
  • Reporting exports are limited compared with warehouse-native tools, so teams that want campaign data alongside finance data end up pulling it through the API on a schedule.
  • Contracts are annual and negotiated per traffic band, so a seasonal spike in visitors can push you into a renegotiation rather than a metered overage.

Klaviyo

  • The free plan caps active profiles at 250 and sends at 500 emails a month
  • Pricing scales with stored profile count rather than with messages sent, so an unengaged list costs the same as an active one
  • SMS is metered separately, with only $5 of mobile messages included on the free plan
  • Paid tier prices are not published on the pricing page and depend on profile count

Answered from the vendors’ own pages

Yes. It is a supported primary channel with catalogue and template message support, though WhatsApp conversation fees from Meta are passed through and are separate from the licence.

Klaviyo: Is Klaviyo free?

Klaviyo has a free tier covering up to 250 active profiles, 500 email sends per month and $5 of mobile messages per month, with 10,000 Composer credits. Email support on the free tier lasts only the first 60 days.

Insider: Can we run it without vendor help?

You can, but the pricing assumes a managed relationship. Teams with strong in-house campaign operations often find they are paying for services they do not use.

Klaviyo: How much does Klaviyo cost?

Klaviyo does not publish a paid rate card on its pricing page. Paid tiers are priced by active profile count and message volume, and a figure is produced through the plan estimator rather than shown as a list price.

Source
Insider: Does it work for B2B?

Rarely a good fit. The segmentation, recommendations and channel mix are built around high-frequency consumer behaviour.

Klaviyo: What counts as an active profile in Klaviyo?

Klaviyo defines active profiles as the contacts eligible to receive marketing, and the free tier is limited to 250 of them. Profile count is the main input to what a paid plan costs.
